2005 IEEE Wireless Communications and Networking Conference, WCNC 2005: Broadband Wirelss for the Masses - Ready for Take-off
作者: Gossain, Hrishikesh Joshi, Tarun Cordeiro, Carlos Agrawal, Dharma P. OBR Center for Distributed and Mobile Computing Department of ECECS University of Cincinnati Cincinnati OH 45221-0030 United States Philips Research Wireless Communications and Networking Department Briarcliff Manor NY 10510 United States
In this paper we propose a Directional Routing Protocol (DRP) for MANETs. DRP is an on-demand directional routing protocol which assumes a cross layer interaction between routing and MAC layer. The main features of DR... 详细信息
